Swift Programming

Swift is a compiled programming language created for iOS, OS X, watchOS, tvOS and Linux development by Apple Inc. Swift is designed to work with Apple's Cocoa and Cocoa Touch frameworks and the large body of existing Objective-C code written for Apple products. Swift is intended to be more resilient to erroneous code ("safer") than Objective-C and also more concise. It is built with the LLVM compiler framework included in Xcode 6 and later and uses the Objective-C runtime, which allows C, Objective-C, C++ and Swift code to run within a single program. A second free implementation of Swift targets Microsoft's Common Language Infrastructure (a.k.a. .NET) and the Java/Android platform.

Hello, I am developing a type of "note taking" App in iOS for a specific vertical market (its not just a simple note taking App, but note taking is a basic function of the App). A user will use the App to collect data (text and images) and store them in permanent storage (a data file of some sort.)

The iOS App will have a companion desktop application for the Mac, which will take the data in the "data file" collected by the iOS App and perform more analytical processes. So, the system is a two part system. One part is the iOS App. portion (the data collection part) and the second portion is the Mac desktop application part to perform more in-depth analytical functions.

*** My question is: How can I share the "data file" between the iOS device and the Mac portion of the system. By "share" I mean, how do I collect the data on the iOS App, put it into a permanent storage file and then send that file to the custom Mac desktop application?

Note: I am not asking how to share unassociated files between devices.

Also, if anyone has an example of how to create Apps with data storage, for use in CocoaTouch Mac applications, I would greatly appreciate it. I have not found any tutorials that show how this is done in a practical manner.

I have a web site that I want to convert to an app. www.etraxc.com and www.my-etraxc.com How do I go about finding someone who would do that for a reasonable amount and what is the typical cost structure for something like this?

I'm currently looking at building a small basic app that a few of my customers are looking for, however they all want it as their own unique app so I will need to whitelabel each release from one core set of code, instead of managing several different sets of code / apps.

All companies will have the exact same app features (which are very basic), however I will need to change the 'logo', 'app name' and 'main UI color' for each release.

Swift / iOS and Android Studio seem to have their own 'Whitelabel Management' feature so that you can have one code base and release variable releases from the code base.

So, you build one core app, and then you can release different builds with the variable settings.

QUESTIONS
01 - Has anyone ever used this approach before, and if so do you have any advice?
02 - Is anyone aware of any software (outside of Swift and Android Studio) that will manage code like this, as I might go the Hybrid approach with React Native.

I am very new to writing iOS apps - in fact this is the first app I am writing. In general it is working, but on first load it is very slow to load the data (which is gets from a web service). I added some timers to sections of the script and believe I have narrowed down the area that is slow.

Briefly the process is:

Get the article data (in JSON) and save it to an Article object and update table cell

For each article check if it has an image, if so access the image JSON to get the URL

Download the image and save to Article Object and update table cell

Display table and use placeholder image if article does not contain an image

It appears to be point 3 that causes the 'freeze'. In subsequent uses of the app it checks the saved array of Article Objects and loads data from there, and then only adds new / updated articles and deletes old articles and therefore is much quicker.

While it is useable I would like to load the table with the text as soon as it is available and then load images in the background, save it to the object and refresh the cell once it is available. While there are articles online with code I cannot seem to get them to work. Either I am left with the app waiting for all the images to load, or just getting the placeholder image for all articles.

My code (for this) is currently in a couple of places. Loading the JSON is in the TableViewController viewDidLoad() and the image …

Hello,
Are there any good products, sites or services that can be used to basically develop a prototype app for planning purposes and relaying information to others like graphics, dev etc.? Something that can be used as a kind of project manager to build a app.

So lets say you have a idea for a app but want to do a rough, not flashy, draft of the layout and mock actions for buttons etc. So if you tap here then this screen pops up type of thing so not actually coding the app but just some type of WYSIWYG interface to help test out the flow of the design before spending time and money on the actual coding and graphics etc.

Is there a way to do Xcode development and maintain the projects in such a way that if I have to switch between 2 - 3 macs I still have access to my projects. Right now doing a course on Swift and that would be helpful

But when i run/debug the project in browser emulator, the device is still portrait.
I tried using net.yoik.cordova.plugins.screenorientation plugin with following code nad it didn't work either (alert worked)

I am a rookie with programming but wanted to delve into programming for Androids. What language should i use? or what development program.? also, does this language translate to coding pretty well if i wanted to create the same app for ios.
any commentary would be greatly appreciated

As all "great" projects start, my wife asked me to build an app for their small teacher organisation. I'm new to development of IOS, but have worked in java, so I've made progress in getting up to speed with Swift and building up the framework of the app and getting it operational.

However, it dawned on me that I don't have an understanding of do's and don'ts when building a secure app. The books I've read focused on the UI more than the data itself. With the current project, I don't have risk that I need to worry about. But would like to use this app as a ginnie pig. I'd like to know what are things I should be doing or adding into a iOS app to ensure it's secure and protected. I am not asking from a UI Pov (Apples KB documents provided me with that), but more on the lines of protecting the data if I was sending secure data from the app to a cloud DB (I.e. Firebase) or storing user profile or credentials in the apple "Core Data".

I have a swift 3 app that uses Alamofire to connect to a web service and get data. All working but once I am done with the data (inserted into Core Data) and exit the Alamofire closure, the memory held by the variable holding the data is not released. See code below: The json variable below will hold to 25MB of memory. The JSON type is Freddy JSON. How do i identify why this memory is not being released

So I am going to write an app in swift for iPhone. It is going to have a lot of multimedia, many gigs that will be written to it.
Right now I am thinking of storing the data as files, and syncing them to the cloud. But what about using DB? can a DB handle large multimedia files? Should I?
I have never written an app before, so any general direction before I start to avoid long term issues would be appreciated.

When working with reverse geocoding some address could be ambiguous for given location and the returned array of placemarks can contain multiple values (address gets multiple hits). This happens very rarely. Usually practice is to take first or last object from given array. So, I want to know why is this common practice. I've looked in Apple documentation and they also took object at index 0. Does the first object contains the most accurate address if the array of placemarks contains more than one object for given location (lat, long)? Thanks for your answers.

I m looking for somethg to post in our corporate IT security 'current banking breaches events': last one I wrote was the Bangladesh banks Swift funds theft in Feb. Think last May another bank fell victim to a Swift funds fraud too.
